Turner, Detroit's first-round pick in last year's draft, was expected to make his third start of the season for the Whitecaps and his next start has yet to be rescheduled.

Whitecaps starter Victor Larez made the spot start in place of Turner and allowed six hits and one run in 5 2/3 innings en route to a 3-0 loss to the Dayton Dragons.

Turner, recently named the Tigers' No. 1 prospect in their organization by Baseball America, has allowed seven hits and one run for a 1.00 ERA in his previous two starts combined.

Turner, who has yet to record his first professional career win, signed a $4.7 million bonus -- the largest ever for a high school pitcher -- as part of the $5.5 million major league contract he signed with Detroit last season.
